ll M PROVEM ENT IN CULTIVATO RS.

To all whom it may concern:

Be it known that I, WILKENsoN FUnNAs, of Ononwa, in the'county of Louisa and State of Iowa, have invented a new and Improved Oultivator; and I do hereby-declare that the following is a full, clear, and exact description of the same, reference being had to theaclcompanying drawings, forming a part of this specification, in which- Figure l represents a plan or top view of this invention. Fig. 2 is a longitudinal vertical section of the same. Fig. 3 is a detached view of the device for adjusting the depth of l Vpass over the growing plants.

- The invention relates to those parts which serve to adjust the plows to the width of different rows, to give to them a lateral motion while in operation, and to throw them out of the ground while turning or passing an obstruction.

' To enable those skilled in the art to make and use my invention, I will proceed to describe it.

A represents a frame, made of wood or any other suitable material, and supported by two axles, O, which rest in the hubs of wheels'B. The axles are turned up so as to raise the frame nearly to the full height of the wheels,

and they are fastened to the outside timbers of the frame, throwing the wheels far enough apart to straddle one row.

D D are two beams, which are hingedy to standards that are secured to the front end of the frame A. The rear ends of these beams are connected to each other by a secondary frame, b, which extends up high enough to clear the growing plants, and in front of the drivers seat S, so that a lateral motion can be imparted to said beams with the hands, if desired. Plows E E are secured to said rear ends by means of standards c, which are connected to theends ot' the beams by meansof hinges and heldin position by braces f, which pass through mortises in the same, and are fastened by wooden pegs g. If the plow runs against an obstruction, the peg gives way and allows the standard to turn back, and injury to the plowV is prevented.

F F are secondary beams, which are secured to the beams D D by pivots h, and held in place by hangers fi, which are secured to the secondary frame b by screws j passing through slots, and to the beams F by pivots, so that said beams can be raised or lowered at pleasure. To the rear ends of the secondary beams the outside plows, G', are secured, in the same manner as the plows E E to the beams D D, by hinges, braces, and wooden pegs, which latter will give way when the plow strikes an Obstruction.

G G are fenders or guards, which are secured to arms lc, extending from the under side of the beams O, and the object of which is to shield the growing plants from clods. The beams D D are suspended by means of straps or ropes l from levers H, which are pivoted to the front end of the frame A, and which are adjustable up and down by serrated bars m, secured to uprights a, rising from the middle cross-bar of the frame A. These levers extend back to the drivers seat, and by their aid the depth to which the plows cutcan be regulated at pleasure. i l

I I are treadles, which are pivoted to the inner sides of the beams D D, and connected by Ameans of hooks c, or other equivalent means,

to the straps l, from which the beams are suspended. Said treadles extend back under the drivers seat, and by stepping upon them the beams D, with all their attachments, can be raised, and the plows can thus be thrown out of the ground at any moment when it may be desired.

The operation isr as follows: The driver oc cupies the seat S, and when he has arrived on the field he adjusts the plows to the desired depth by lowering the levers H. His feet are placed on the secondary beams `F F, and by their aid he can keep the plows down in the ground, or impart to the same a lateral motion to accommodate them to the varyingI direction or width of the furrows. If the plows meet with an obstruction which the driver desires to avoid, he can raise them up by stepping upon the treadles,and let them down again after havin g passed the obstruction, and

at the end of the field he can also raise the plows.l until he has turned round and is ready. to kstart again.

Thus 'it will be seen that the driver has perfeet control over-the position of the plows, and

he can regulate that position instantaneously entirely by the action of his feet.

What I claim as new, and desire to secure by Letters Patent, is
